Description

A kind of baffle

The utility model relates to a kind of Light barrier for automobile plate, or claims sun shield.

In the equipment of existing automobile, can be described as more perfectly, but for chaufeur, also have a problem to fail fine solution, the irradiation of the big light of opposite car when being sunshine or night travel, the glasses that make automobile driver are tired and cause the generation of traffic accident.Chinese patent ZL96236818.0 discloses a kind of antifatigue high-visibility safe driving automobile mirrors and the disclosed antifatigue high-visibility of ZL97246013.6 safe driving automobile folder mirror.The former is because its structure is simple and crude, and people are difficult to accept and can't implement; Be clipped on existing automotive sunshade panel below when the latter uses, have following shortcoming: 1, inconvenient operation, 2, can't adjust its high and low degree, 3, easily come off during automobile vibration, safe reliability is poor.

The purpose of this utility model is to overcome the shortcoming of the above automobile mirrors and the existence of automobile folder mirror, design a kind of its profile Light barrier for automobile plate similar to existing automotive sunshade panel, or title sun shield, make it can eliminate the influence of sunshine or the big light-illuminating of opposite car at night effectively to chaufeur, reach the strong thorn of decay light no-glare, simultaneously can improve visbility and haze-penetrating capability, can regulate the height of anti-high light eyeglass again easily, eyeglass is transferred to suitable position, use with the chaufeur that adapts to differing heights.Satisfy the requirement of automobile driver safe driving.

The utility model comprises eyeglass and the framework that clamps eyeglass, and eyeglass is an optical mirror slip, and the connecting device that can be installed on the automobile cab front upper place is arranged on the framework, in the framework inboard, the groove for the assembling eyeglass is arranged, and it is characterized by; Framework is the n shape framework of lower opening, fixing len and the lifting eyeglass placed before and after being equipped with in the frame slot, and the self-locking device of lifting eyeglass, on the surface of fixing len, part has an anti-high light rete above it, at the lip-deep upper section of lifting eyeglass, an anti-high light rete is arranged also.Anti-high light rete can adopt advanced specialized apparatus to make vacuum coating.The material of plated film such as selenium, chromium, tantalum oxide, silicon dioxide, bismuth oxide, aluminium oxide, silicon monoxide, magnesium flouride, zirconia, titanium etc., can adopt wherein a kind of or some kinds, adopt different parameters, index and advanced method of operation to be made, be processed into the vacuum coating that meets thickness requirement and satisfy high light rate of attenuation technical index.Certainly, anti-high light rete also can be dyeing, color spray or pad pasting, though dyeing, color spray or pad pasting technology are simple, effect is than vacuum coating difference.

The utility model, described lifting eyeglass self-locking device can two row Zhu Keng of corresponding coupling with hoodle constitute on hoodle in framework vertical direction two grooves and the lifting eyeglass by being arranged at.Lifting eyeglass self-locking device also can constitute by being arranged at the tooth bar that should mate with gear mesh on gear in framework vertical direction two grooves and the lifting eyeglass.

The utility model in order to make the lifting of lifting eyeglass smooth and easy, can be provided with a lifting eyeglass guide rail, is made of the convex tendon of corresponding coupling with groove on groove that is arranged at a side in the framework vertical direction groove and the lifting eyeglass.

The utility model, the outer cover that forms by leather sewn that can also supporting be complementary with the Light barrier for automobile plate.

The utility model can be fixedly mounted on the position that the automobile cab front upper place is original sun shield by its connecting device.The height of lifting eyeglass can transfer to suitable position easily and realize self-locking according to the height of chaufeur.Night travel or daytime are during the burning sun down train, because anti-high light rete can reflect away opposite car light high light or solar glare, the high light rate of attenuation reaches more than 80%, high light is passed through after the anti-high light rete, its light becomes soft, and chaufeur is then faced the place ahead by the zone of nonreactive high light rete, and the opposite vehicle is in time dodged in correct judgement, safe driving, the accident that prevents takes place.Realize anti-burning sun on daytime, keep off accent light night, increase the purpose of the preceding brightness of square car.If the bright day gas situation down train of frontlighting again by day in the time of needn't using baffle, can be pushed into the extreme higher position to the lifting eyeglass, put outer cover after, its using method is identical with existing sun shield.

Following embodiment will further specify structure of the present utility model in conjunction with the accompanying drawings.
